I just replaced my old HKS turbo timer type 0 with this new one and it is slick. Such a small display and the Control Unit Case can be put anywhere as well. I have mine under the dash by the fog light switch.
Just trying to figure out where to put the display.

 

cut a slot in the column and mount it in there.

or throw it in the position where the stock clock is..

 

That sounds like a cool idea
